First measurement of prompt and non-prompt D[ast]+ vector meson spin alignment in pp collisions at √s = 13 TeV
This letter reports the first measurement of spin alignment, with respect to the helicity axis, for D⁎+ vector mesons and their charge conjugates from charm-quark hadronisation (prompt) and from beauty-meson decays (non-prompt) in hadron collisions. The measurements were performed at midrapidity (|y...
